How to optimize the model

Optimization of your model is a key aspect of dynamic analyses which aim at ensuring accurate results at the minimum calculation effort. Once you have setup your model components and linked them as appropriate, it is recommended that you perform basis checks based on static analyses. Inspection of results such as tension and curvature along the lines would help you ensuring that the number of elements used to mesh the line is optimum and allows capturing peak values (e.g. peak curvature next to the touch down point).

It must be noted that the calculation time may be significantly increased in case the meshing is too fine. It is recommended that you carry out a couple of dynamic simulations with alternate number of elements and check the calculation time along with key results. This is intended to achieve the best balance between accuracy and calculation time.

There are several other parameters that may impact convergence and calculation time, which cannot be all discussed in this section. More information and hints about convergence and optimization may be found in the help topic discussing convergence issues.
